IMPROVEMENT IN COAL-HODS.

Specification forming part of Letters Patent No. 190,514, dated May 8,1877 application filed September 21, 1876.

To all whom it may concern Be it known that I, WILLIAM S. POTWIN, ofChicago, in the county of Cook' and State of Illinois, have invented newand useful Inprovements in Coal-Hods; and I dohereby declare thefollowing to bc a full, clear, and exact description thereof, which willenable others skilled in the art to which my invention appertains tomake and use the same, reference being had to the accompanying drawing,forming part of this specification, in which the figure represents avertical central section of a coal-110d embodying my said invention.

The object of my invention is to improve the construction of thecoal-hod for which I obtained Letters Patent on the 27th day of June,1876, No. 179,132; and to that end my invention consists in thecombination, with the Wood bottom, of a sheet-metal lining; and, also,in providing the lower edge of the body with an inwardly-projectingflange adjusted to pass between the two parts of the bottom, as ishereinafter more fully described.

In the drawing, A'represents the body of the hod, which is made of anysheet metal ordinarily used for that purpose. B is the bottom of thehod, which is made in two parts, 0 and G, and connected together byscrews or rivets a a, as shown and described in the aforesaid LettersPatent. The periphery of the part 0 is beveled inward at an anglecorresponding with the taper of the body, and so as to fit closelyagainst the wall of the body at its base, and the part 0 is beveledoutward from the base of the body, as shown at d. The lower edge or baseof the body is turned inward, forming a flange, j, which extends underthe part 0, and between it and the part 0, which prevents the part 0from being forced through the body by the weight of the material in thehod. D is a sheet-metal lining, which rests upon the upper surface ofthe part 0, and is secured thereon by having its edge turned or spunover the periphery of the said part 0, and so that the turned edge ofthe lining will wedge between the periphery of the part 0 andthe wall ofthe body, as shown at g. Y

The object of said lining is to prevent the bottom of. the hod, or thepart 0 thereof, from being worn or burned by the material placed Withinthe hod.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

' 1. In a coal-hod, the combination, with the bottom B, consisting ofthe parts 0 and O, of the sheet-metal lining D, having its edge turnedover the periphery of the part 0, and compressed between the part O andthe body of the hod by the screws or rivets uniting the parts 0 and O,substantially as and for the purpose specified.

2. In acoal-hod, the combination, with the bottom B, consisting of theparts G and G, of the body A, provided with the flange f, adjusted tofit between the parts 0 and 0, substantially as and for the purposespecified.
